Jennifer Lopez’s hair just went from short to shorter, as the starlet posted a sunny Instagram selfie this morning showcasing a shorter-than-ever chin-length chop. She captioned the snapshot, “Short hair don’t care…” While the 45-year-old pop stars’ new haircut is undoubtedly chic, we’re guessing it won’t be long before she pops in her extensions again. But for now, the JLo’s refreshed crop makes for a summer-perfect haircut, and is a glorious addition to the celeb bob brigade.
